Description

Technical Field

[0001] The utility model relates to the technical field of PEM electrolyzers, and specifically to a low-cost and lightweight structural component for a PEM electrolyzer. Background Art

[0002] With the growing demand for clean energy, PEM electrolysis hydrogen production technology has received extensive attention. However, the widespread application of current PEM electrolyzers is restricted by high costs. In general, the structural components of a PEM electrolyzer mainly consist of a base, a blind end plate, a blind end insulating plate, a blind end current collector plate, an inlet current collector plate, an inlet insulating plate, and an inlet end plate.

[0003] Chinese Utility Model Patent Publication No.: CN 220099214 U3, discloses: a PEM electrolyzer. When this PEM electrolyzer is in normal use, the first valve is opened, and the hydrogen generated in the electrolyzer body enters the hydrogen storage tank through the hydrogen discharge pipe to achieve the function of hydrogen storage. When there is a leak in the electrolyzer body, hydrogen enters the accommodation box. At this time, the hydrogen concentration detector detects the hydrogen concentration in the accommodation box and sends the information to the single-chip microcomputer, and the single-chip microcomputer controls the alarm to start alarming. However, this PEM electrolyzer has many structural component materials, is relatively heavy, is prone to bring inconvenience to assembly and transportation, and has a high cost, which is not convenient for popularization and use. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a low-cost and lightweight structural component for a PEM electrolyzer, which can effectively solve the problems in the prior art such as many structural component materials, relatively heavy weight, prone to bring inconvenience to assembly and transportation, high cost, and not convenient for popularization and use.

[0005] The technical solution adopted by the utility model is: a low-cost and lightweight structural component for a PEM electrolyzer, including a blind end plate and an upper end plate. An insulating plate is fixedly installed on the top of the blind end plate, a current collector plate is fixedly installed on the top of the insulating plate, a floor foot is fixedly installed on one side of the blind end plate, a plurality of equally spaced card slots one are opened on the top of the insulating plate, a core is arranged inside the card slot one, a plurality of inlets are arranged on the top of the upper end plate, a support block is fixedly installed on the outside of the blind end plate, a card slot two is opened on the top of the blind end plate, and a reaction area is arranged inside the blind end plate.

[0006] Preferably, a fixing bolt one is fixedly installed on the outside of the floor foot, and the fixing bolt one penetrates through the floor foot and extends into the inside of the blind end plate.

[0007] Through the above technical solution, when installing the floor foot, the fixing bolt one can be rotated, passed through the floor foot, and reach the inside of the blind end plate, so as to realize the quick installation of the floor foot and the blind end plate, and facilitate the subsequent support of the blind end plate.

[0008] Preferably, a hook is fixedly installed on one side of the floor feet. Two hooks are fixedly installed on the outer sides of a set of the floor feet, and the hooks are located on both sides of the blind end plate.

[0009] Through the above technical solution, through the design of the hooks, during the transportation process, the entire electrolytic cell can be lifted by the hooks, which is convenient for the overall transportation of the electrolytic cell and avoids the difficulty in subsequent transportation of the electrolytic cell, resulting in greater difficulty during transportation.

[0010] Preferably, there are two identical sets of the floor feet, fixing bolts I and hooks. There are two identical ones in a set of the floor feet, fixing bolts I and hooks. The two sets of the floor feet, fixing bolts I and hooks are symmetrically distributed about the center line of the blind end plate.

[0011] Through the above technical solution, through the design of the two sets of floor feet, the floor feet only play a supporting role during installation and do not follow the overall electrolytic cell for shipment. By increasing the floor feet, it is convenient for forklift handling.

[0012] Preferably, the thickness of the blind end plate is 70 mm to 80 mm, and the thickness of the upper end plate is 60 mm to 70 mm.

[0013] Through the above technical solution, through the design of the thickness of the blind end plate and the upper end plate, it can not only reduce the weight of the structural parts, making the overall weight of the electrolytic cell lower, but also reduce the overall production cost to a certain extent, which is convenient for popularization and use.

[0014] Preferably, an upper end plate is fixedly installed on the side of the cell core away from the blind end plate, and the upper end plate serves as the negative electrode.

[0015] Through the above technical solution, through the design of the negative electrode upper end plate, the transmission part is connected to the negative electrode, which belongs to zero potential. In the electrolytic cell, not only the inlet insulation design is removed, but also the upper end plate is directly used as the negative electrode, streamlining the insulating plate and the current collecting plate, and reducing the overall weight and production cost.

[0016] Preferably, the blind end plate adopts a double-layer design. Fixing bolts II are fixedly installed on the outer sides of the support blocks. There are two identical support blocks, and the two support blocks are located on the front and back sides of the blind end plate.

[0017] Through the above technical solution, through the design of the two support blocks, the front and rear ends of the blind end plate can be supported, avoiding the overall electrolytic cell from tilting and being damaged during the transportation or use process.

[0018] Compared with the prior art, the present utility model provides a low-cost and lightweight structural part for a PEM electrolytic cell, having the following beneficial effects:

[0019] 1. The low-cost and lightweight structural component of the PEM electrolyzer has its inlet connected to the negative electrode, which is at zero potential. After verification, the insulation design at the inlet end is removed, and the upper end plate is directly used as the negative electrode, streamlining the insulation board and current collector plate, effectively reducing the weight of the structural component and the cost.

[0020] 2. The low-cost and lightweight structural component of the PEM electrolyzer has its feet only serving as a support during installation and not being shipped with the electrolyzer. This not only prevents the whole from being prone to tipping over but also leaves a space at the bottom through the feet, facilitating the handling by forklift and the transfer of the entire electrolyzer.

[0028] Embodiment 1: As Figures 1-5As shown in the figure, a low-cost and lightweight structural member of a PEM electrolytic cell provided by the present utility model includes a blind end plate 1 and an upper end plate 9. An insulating plate 2 is fixedly installed on the top of the blind end plate 1, a current collector plate 3 is fixedly installed on the top of the insulating plate 2, a floor 4 is fixedly installed on one side of the blind end plate 1, a plurality of equally spaced card slots 7 are opened on the top of the insulating plate 2, a core 8 is arranged inside the card slot 7, a plurality of inlets 10 are arranged on the top of the upper end plate 9, a support block 11 is fixedly installed on the outside of the blind end plate 1, a card slot 13 is opened on the top of the blind end plate 1, and a reaction zone 14 is arranged inside the blind end plate 1.

[0029] Specifically, a fixing bolt 5 is fixedly installed on the outside of the floor 4, and the fixing bolt 5 penetrates through the floor 4 and extends to the inside of the blind end plate 1. The advantage is that when installing the floor 4, the fixing bolt 5 can be rotated, passed through the floor 4, and reach the inside of the blind end plate 1, so as to realize the quick installation of the floor 4 and the blind end plate 1, and facilitate the subsequent support of the blind end plate 1.

[0030] Specifically, a lifting hook 6 is fixedly installed on one side of the floor 4, and two lifting hooks 6 are fixedly installed on the outside of a group of floors 4. The lifting hooks 6 are located on both sides of the blind end plate 1. The advantage is that through the design of the lifting hook 6, during the transportation process, the whole electrolytic cell can be lifted through the lifting hook 6, which is convenient for the overall electrolytic cell to be transported, and avoids the difficulty in subsequent transportation of the electrolytic cell, resulting in greater difficulty in transportation.

[0031] Specifically, there are two identical groups of the floor 4, the fixing bolt 5 and the lifting hook 6, and there are two identical ones in a group of the floor 4, the fixing bolt 5 and the lifting hook 6. The two groups of the floor 4, the fixing bolt 5 and the lifting hook 6 are symmetrically distributed about the center line of the blind end plate 1. The advantage is that through the design of the two groups of floors 4, the floor 4 only plays a supporting role during installation and does not follow the overall electrolytic cell for shipment. By increasing the floor 4, it is convenient for forklift handling.

[0032] Embodiment 2: As Figures 2-5 shown, as an improvement to the previous embodiment.

[0033] Specifically, the thickness of the blind end plate 1 is 70 mm to 80 mm, and the thickness of the upper end plate 9 is 60 mm to 70 mm. The advantage is that through the design of the thickness of the blind end plate 1 and the upper end plate 9, not only can the weight of the structural member be reduced, making the weight of the overall electrolytic cell lower, but also the overall production cost can be reduced to a certain extent, which is convenient for popularization and use.

[0034] Specifically, the upper end plate 9 is fixedly installed on the side of the core 8 away from the blind end plate 1, and the upper end plate 9 serves as the negative electrode. The advantage is that through the design of the negative electrode upper end plate 9, the transmission part is connected to the negative electrode, which is at zero potential. In the electrolytic cell, not only the insulation design of the inlet 10 is removed, but also the upper end plate 9 is directly used as the negative electrode, which simplifies the insulating plate 2 and the current collector plate 3, and reduces the overall weight and production cost.

[0035] Specifically, the blind end plate 1 adopts a double-layer design. A second fixing bolt 12 is fixedly installed outside the support block 11.

Through the design of the lifting hook 6, during transportation, the entire electrolytic cell can be lifted through the lifting hook 6, facilitating the transportation of the overall electrolytic cell and avoiding difficulties in subsequent transportation due to the inconvenience of the electrolytic cell, resulting in greater transportation difficulty. Through the design of the two groups of anchors 4, the anchor 4 only plays a supporting role during installation and does not follow the overall electrolytic cell during shipment. By increasing the number of anchors 4, it is convenient for forklift handling. Through the design of the thickness of the upper end plate 9 of the blind end plate 1, not only can the weight of the structural components be reduced, making the weight of the overall electrolytic cell lower, but also the overall production cost can be reduced to a certain extent, facilitating popularization and use. Through the design of the upper end plate 9 of the negative electrode, the transmission part is connected to the negative electrode, which is at zero potential. In the electrolytic cell, not only the insulation design of the inlet 10 is removed, but also the upper end plate 9 is directly used as the negative electrode, streamlining the insulating plate 2 and the current collector plate 3, reducing the overall weight and production cost. Through the design of the two support blocks 11, the front and rear ends of the blind end plate 1 can be supported, avoiding the overall electrolytic cell from tilting during transportation or use, resulting in damage to it.
